The distance between the two points is less than 50 km, this distance he will cover in 9 hours and will travel in 3 hours. How many kilometers is the distance between two points.

Answer: the distance between the two points is 36 or 45 km.

Estimating the distance traveled comes down to finding the most probable common multiple of less than 50 for the numbers 9 and some two unknowns, since the distance traveled is equal to the product of speed and travel time.

1. The average speed of movement of a person when walking is approximately 5 km / h. That is, his distance traveled in 9 hours will be:

9 * 5 = 45 km.

It can be assumed that with such a long travel time, the average pedestrian speed will be less and will be 4 km / h. Then the traversed path will be equal to:

9 * 4 = 36 km.

2. The usual speed for, for example, a cyclist is 12 – 15 km / h.

A cyclist will cover a distance of 45 km in 3 hours at a speed of 15 km / h, and a distance of 36 km at a speed of 12 km / h.



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
